An image blur suppression device suitable for a camera which compensates for low frequency camera motion without increasing the length of the camera in the optical axis direction and without posing limitation on the design of the camera. The image blur suppression device compensates for image blur by damping vibrations of a camera body to a compensation optical system using the inertia of a balance member. An oscillation mechanism unit is equipped with a first rotation member, one end of which is supported by the camera body so that it can rotate freely and the other end of which is fitted with the compensation optical system. A second rotation member is supported by the camera body so that it can rotate freely. The second rotation member has one end fitted to the first rotation member and the balance member attached to the other end.
